My invention relates to improvements in apparatus for delivering sirup for bottle fillmg machines such, for nstance, as bottle machines tor bottling carbonated beverages;

5 Heretofore such "structures haveicomprised a sirup receptacle which is reciprocable to be moved down upon'th'e bottle and up away from the bottle. This receptacle has been supported by'a reciprocating cylinder and in order to insure the discharge of the sirup from the receptacle, there has been provided a plunger. tacle comes to rest on the top ofgthe bottle,

continues its downward movement in the. re-

ceptacle. insuring the discharge of the sirup in the receptacle. ,Heretofore thisplunger has been raised in the receptacle by the in-' coming sirup which iSdlSOllfil'gGCl'iIitO'ftllG receptacle afterthe charge therein has been delivered to the bottle; Some sirups are heavier or thicker than others and as a result require greater weight in the plunger to force the same out of the receptacle; How; ever, heretofore the weight ofthis plunger has been limited, due to the fact that it has had to be raised by the incoming sirup and in order to getsuflicientforce, the sirup from the storage tank. has had to have considerable head.

it has been found infsome" instances that this is impracticable due to the limit ofthe ceiling height of the bottling factory;

It "is one of the objects of my presentindesired.

For the purpose of disclosing my invention,v embodiment; thereof g I have illustrated one in which: i a The figure is vention.

In the embodiment of the invention illus-I trated, I provide a' cylindrical support "1 which is adapted to @be secured to arecipro- This plunger, 1 when the recep-- 7 It' has been necessarytherefore to place the storage receptacle at a considerable height above the machine and a longitudinal section ofa" sirup" filling apparatus embodying my ineating part of the machine and is adapted i engagin'gthe top dot the cylinder 1 and the Y ,lowerend engaging an annular flange 5' at the lower end of the receptacle 2. The rela- ,tive movement in one direction between the cylinders- 1 and the-receptacle'2, under-the in=- fluence'ofthe spring '3, is limited by stoponuts'6 at the top of guide rods" 7, which-pro} ject through the-top of the cylinder 1, and'at their lower ends Vare"screw threaded iintobosses 8 on thesides of the receptacle 2; i

"The bottom "ofthe receptacle 2 is provided; with a dischargeandinlet port 9, which dischargesthr'ough an opening 10 into a spout" 11 having atitslower end a mouthpiece 12 adapted, when vthe structure is lowered, to engage. 'wit h the top of the bottle. I This mouthpiece is providedwith a washer 13. The spout has a slight movement relative to the bottom'of the receptacle 2 and is biased" toward the outermost limit ofthis movement by a coiled spring 14 interposed between thebottom of the receptacle and the mouthpiece 12. The flow wofsirup from-the receptacle 2 and through the port 9 into the mouthpiece 11, and the flow of sirup from the supply" '-pipe:15 throughthe port 16 into the recep tacle is controlled by a valve 1'1 which when I the receptacle" is in its raised position, closes the spout 11 and allows the flow of sirup from the port 16 into the receptacle 2. -When, how

ever, the receptacle is in its'lowermost posi-- tion and in contact with the bottle, the valve 1S 1n11ts raised positionishutting off the flow of sirup rom the port 16 and opening access I 3 he'spoutlL p a i Operating within the receptacle 2 is a plunger 18,theweight of which may be increased by an annular removable weight 19," V

and which is provided with a threaded stem 20. -This stem is threadediinto the lower end of an elongated cylindrical nut member 21,

whic'hprojects through a top opening in the cylinder 1 and is provided at its upperend: with an annular-flange, 2 by which it is suported from the top of the cylinder and which "is orovide'd with openings adapted to receive the downward movement of the receptacle 2,

the cylinder 1 can continue in its downward movement. This continued downward movement leaves the plunger unsupported and due to the weight of the plunger and its associated arts, it will move downwardly underthe in uence of gravity thereby forcing the sirup in the chamber 1 out through the spout 11 and into the bottle, the valve 17 having been raised when the mouthpiece comes in contactwith the neck of the bottle. As soon as .the plunger reaches the lowermost limit of its downward stroke, the cylinder 1 commences its upward stroke, its top engaging the flange 22 first raising the plunger and the flange 22 then engaging the stop nuts 6, thereby raising the receptacle 2. This permits. the valve 17 to drop back on its seat over the mouthpiece 11 closing the discharge opening of the receptacle and opening the inlet opening of the receptacle sothat sirup may flow from the supply pipe 15 into the receptacle.

, It will be noted that the upward movement of plunger 18 relative to receptacle 2 is accomplished by spring 3 and therefore, a very slight head is sufficient for causing the sirup to flow into the receptacle.

I claim as my invention:

1. In a sirup dispenser for bottle filling machines, the combination with. a reciprocating cylinder, of a sirup receptacle mounted therein, movable with and relatively to said cylinder, a filler spout carried by said receptacle and having a limited movement relative thereto, a valve operated by said spout for controlling the delivery of sirup to and from said receptacle, a plunger operating in said receptacle and having a stem, and a nut in which said stem is adjustably mounted,

said nutbeing movable in one direction with respect to said cylinder by gravity and in the other direction by said cylinder.

2'. In a sirup dispenser for bottle filling machines, the combination with a reciprocating cylinder, of a sirup receptacle mounted therein, movable with and relatively to said cylinder, a filler spout carried by said receptacle and having a limited movement relative thereto, a valve operated by said spout for cont-rolling the delivery of sirup to and from support and receptacle for causing said sup- 7 port and receptacle to move together while permitting a continued movement of the support after the receptacle has come to rest, a

plunger in said receptacle and a support for said plunger carried by and movable rclatively to said reciprocating support.

4. In a sirup dispenser for bottle filling machines, the combination with a reciprocating support, of a sirup receptacle having a delivery spout, a connection between said receptacle and support for moving the receptacle and support together while permitting a continued downward movement of the support after the receptacle has come to rest on its downward movement, a plunger in said receptacle and means engaged by said support'for raising said plunger as the support moves upwardly while permitting the support to move downwardly independently of the plunger.

c 5. In a sirup dispenser for bottle filling machines, the combination with a reciprocating support, of a sirup receptacle having a restricted outlet port at its lower end, means for-connecting the receptacle and support to cause the receptacle to move with the support, while permitting a continued downward movement of the support after the downward movement of the receptacle has stopped, a plunger in said receptacle and movable downwardly with respect thereto at a slower rate than said support and means connected to said plunger and adapted to be engaged by said support for raising the plunger with the support.

6. In a sirup dispenser for bottle filling machines, thecombination with a reciprocating support, of a sirup receptacle, a connection between said support and receptacle efiecting limited downward movement of the receptacle with the support permitting a continued downward movement of the support after the downward movement of the receptacle has stopped, a plunger in said receptacle, and lost-motion means permitting said It JAMES KANTOR.
